What is new for vMotion in vSphere 6.0?
Cross vSwitch vMotion
- vSS to vSS is supported
- vSS to vDS is supported
- vDS to vDS is supported
- vDS to vSS is NOT Supported
Cross vCenter vMotion
- Ability to move a VM to a new vCenter Server
- Even do it without having a shared datastore between the source and destination vCenter aka “shared nothing migration.
- Requirement for the source and destination vCenter Server to belong to the same SSO domain
- When the VM is migrated things like alarms, events, HA and DRS settings are all migrated with it.
Long Distance vMotion
- Remember that the max tolerated latency was 10ms for vMotion?
- With this new feature that just went up to 150ms
- Uses socket buffer resizing techniques to ensure that migrations succeed when latency is high.
- Note that this will work with any storage system, both VMFS and NFS based solutions are fully supported
Network Enhancement
- vMotion traffic is now fully supported over an L3 connection
- So no longer is there the need for L2 adjacency for your vMotion network
Full support for vMotion of Microsoft Cluster virtual machines
- It's newly introduced in vSphere 6.0. Note that these VMs will need to use physical RDMs and only supported with Windows 2008, 2008 R2, 2012 and 2012 R2. Very useful if you ask me when you need to do maintenance or you have resource contention of some kind.
